everything in minimum number of functions
4. The in-memory of R is just 10% of your total RAM (Correct me if wrong).
Make sure most of it is used for processing and not storing
Hope this will help. Kindly suggest if I have misunderstood anything.

Greetings,
Thanks Jeff. I appreciate your 'to the point' explanation. Will read into
it more.

try this:
colnames(df)<-df_names[1:ncol(df),"name"]

You can try this one too.
#Set the directory to a path where all the files to be read are stored
TabletoRead=list.files(pattern=".txt")
I_Step=unlist(lapply(TabletoRead,function(tab){
srno<<-ifelse(exists("srno"),(1+srno),1)
Temp=read.table(tab,header=T,s
eval(parse(text=paste0("cvtest$",lambda.rule)))
I hope this works.

Can you please elaborate. What are the negatives about the method

If you have a data frame "df" with a column "JT"
Try this one:
str <- "df$JT == 12"
fun<-function(str){b<-eval(parse(text=str))
return(b)}
fun(str)

This will work fine

Hi All,
I have used windows R.
We can also write like this:
A <- read.csv("C:/Users/Anthi/Desktop/R/A.csv",header=TRUE)

This will give you all the web dat in an HTML-Text format.
You can use
Try this;
help(anova)
I have used this in R-2.14.1
It has worked fine for me. Hope it works for you as well.

Hi,
Another way of doing may be like this;
a <- c("d", "d", "j", "f", "e", "g", "f", "f", "i", "g")
b <- c("a", "g", "d", "f", "g", "a", "f", "a", "b", "g")
ta <- table(a)
tb <- table(b)
Function<-function(Tab1,Tab2){elements=sort(unique(c(names(ta),names(tb
OP=lapply(1:length(elements),FUN
This is what I think;
Hive internally distributes the data. If you have set up Hive on single
core it will fetch the query results from that core. If you have multi-core
system on which you have setup the Hive, it will search all the cores for
the query submitted and results would be compiled toge
I do not know about the packages that you mentioned. I am trying to answer
your query based on the term "socio-linguistic analytics".
There are packages like "OpenNLP","OpenNLP.en","tm (Text Mining)" that
might be of your interest.
Best,

Try the following code.
It is basic but effective;
*setwd("/home/user2/Documents")*
*Test_matrix=read.csv("Trial.csv",header=T) # The 1st table that you have
considered
*
*Test_matrix=as.matrix(Test_matrix)*
*Writer=function(mat){u=unique(mat[,"Subject"])*
*l=length(u)*
*dummy=lapply(1:l,FUN
We can have something like this;
*Data1<-data.frame(Site1=c(5,NA,4),Site2=c(3,2,4),Site3=c(NA,5,NA))
Data2<-data.frame(TraitType1=c(1,2,3),TraitType2=c(2,4,2),TraitType3=c(5,1,1))
*
*rownames(Data1)<-paste("Species",1:3)*
*rownames(Data2)<-paste("Species",1:3)*
*User_Defined=function(dat1,dat2
You can look for different versions of that package and try manually
installing the lower version.
